Abstract
A computer-implemented method retrofit for decoding video in a video decoding chipset is disclosed. The method comprises receiving a video signal and a picture improvement signal; decoding the video signal to create decoded video; deriving, from the picture improvement signal, pixel touching information to be used to modify a pixel of the decoded video; and causing a graphics feeder of the video decoding chipset to overlay the pixel touching information onto the decoded video.
